It is very interesting to see a U.S. President in a tech forum taking to Internet people.
In above's video you can watch former President George W. Bush stopping by the Facebook headquarters and talking to Mark Zuckerberg. Bush is there promoting his new memoir, Decision Points.
I was not a Bush fan but I must say that now he appears cool, funny, open minded. He gets continuos round of applause from the tech audience. Congratulations Mr. President!
